Answer:
B.
Step-by-step explanation:
Well to find BC, you have to know B and C
B = (-4, 4)
C = (-4, -1)
The distance is:
√(4 + 1)^2 + (-4 + 4)^2
√25

Answer:
The equation of the parabola in vertex form is 
.
Step-by-step explanation:
Since the directrix is of the 
, then the equation of the parabola in vertex form is of the form:
(1)
Where:
- Dependent variable.
- Independent variable.
- Least distance between focus and directrix.
, 
- Coordinate of the vertex.
The least distance between focus and directrix is determined by Pythagorean Theorem:
Now, we determine the location of the vertex by the following vectorial formula:
(2)
If we know that and 
, then the location of the vertex is:
And the equation of the parabola in vertex form is .

Step-by-step explanation:
C.) Buried under mud. Fossils form when the mud traps the plant/animal and hardens, cementing the form of the body, which is a fossil.
5.1 = m/0.3
1.53 = m
